How Does This Dyno Chart Look?

[GTRClintR32]

If anyone could help me understanding my dyno print out. I feel it is not putting the power on earlier enough plus it seems to drop down right at the end.....I am unsure why?

A good start would be to tell us what exactly you have running in the car.

Hi there,

Here is a list of all the things that I have done to the car since I got it. I am really a beginner with this car....

HKS cat back exhaust, HKS fully adjustable suspension, cross drilled rotors all round, Apexi Power FC computer, heavy duty clutch with lightened brass button flywheel, Eboost 2. argo h beam rods, acl forged pistons, arp head studs, N1 oil pump, N1 water pump, gates racing timing belt, tomei 260 poncams, tomei adjustable cam gears, mls metal head gasket, 2 garrett 2860 turbos, tomei sump baffle

Who also would you recommend for a good tune? As far as I know the adjustable cams have'nt been adjusted also

Thanks

There's at least four different sizes of 2860s - do you know which ones you have? The larger ones will have more power potential but produce power at higher rpm. Have a look through the RB26 turbo upgrade dyno sticky in Forced Induction find sheets to compare to.

Not many people tune at 12.5 AFR when the boost is up - typically its more like 11.5 or 12, which will be safer for the motor. Maybe they're running less timing to try to compensate??

Did you ask Envy what happened at 185kms?

AFAIK Jim at Croydon racing and Yuvas at Unigroup are among the most respected tuners in Sydney.

The good news is i've seen worse

The bad news is i've seen plenty a lot better

But, without knowing which 2860's, how much boost and a myriad of other things... It's hard to say where yours sits exactly.

My guess, being only 320rwkw, its the smaller ones, in which case you have some issues.

I've never heard on "envy", are they well versed in RB performance? IF not, your money might well be better spent at a number of other places.

Thanks for the advice so far.....I am certain they are the dash 5's. If that makes any sense. The car was'nt actually tuned at Envy, they just had a Dyno Day which I took my car to.

Envy won't able to confirm what was happening at the end there on the spot, what suggestions would any of you guys have?

By the way I think the boosts are set at 15, 17.5 and 20 PSI

Thanks
